11 Claims.

This invention relates to a valve, particularly a measuring valve and while the invention has many applications, it has great utility in restaurants, hotels and like places for dispensing cream or milk.

Measuring valves are'now commonly used in restaurants and like places for dispensing a certain amount of cream from a container into cups in which coffee is served. It is desirable to have a measuring valve of such structure that it is easily operated, can be easily cleaned and is maintained in proper working conditionwith little attention.

It is an object of thisinvention, therefore, to. provide a measuring valve comprising a casing having a cylindrical chamber therein with receiving and discharge ports communicating with said chamber, a shell-like member received in said casing and oscillatatable in said chamber also having "inlet and outlet ports adapted to register respectively with said receiving and discharge ports, said casing comprising a movable part which partially embraces said shell and is spaced from the stationary part of said casing so that provision is had for moving said movable part to properly engage said shell whereby wear between said parts may be taken up.

It is a further object of the invention-to provide such a valve as set forth in the preceding paragraph in which said movable part of said casing is held in positionsnugly embracing said shell by resilient means.

It is still another object of the invention to:

provide a valve structure as setforth above hav-' ing said casing and shell, said casing having a fixed part and a swingable part, said swingable.

part being separated from said stationary part alonga plane extending substantially diametrically through the chamber in said casing and be ing spaced slightly from said stationary partat its free end whenin position engaging said shell together with means holding said swingable part inposition snugly engaging saidshell so that wear on said casing and shell may be taken up and said shell may be removed from said casing inven- I prising a casing having a cylindrical chamber therein and receiving and discharge ports communicating with said chamber, a shell oscillatable in said cylindrical chamber and having inlet and outlet-ports adapted to aline respectively with said receiving and discharge ports, said casing being divided along a plane extending substantially diametrically of said chamber and thus having a fixed part and a movable part hinged thereto, said fixed part havinga member pivoted thereto at the side opposite the connection to said movable part, a lever pivoted to said swingable member and a spring acting on said swingable member, said movable part having means adapted to be engaged by said lever whereby said movable part may be moved to position engaging said shell and said means engaged by said lever and said lever swung past a dead center position to hold said movable part in snug engagement with said shell under tension of said resilient means, the free end of said movable part being spaced from said. stationary part of saidca sing whereby wear between said casing and shell will be'taken up by said resilient means.

Theseand other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawing, in which like reference characters refer to similar parts throughout the several views and in which:- I V Fig. 1 is a view in side elevation of said valve; Fig. 2 is a top plan view, some parts being broken away and others shown in horizontal section; a

Fig. 3 is a vertical section taken on line 3--3 of Fig. 1 as indicated by the arrows, some parts being broken away and parts indicated in differ ent positions by dotted lines; and Y Fig. 4 is a perspective view of the shell member used. v l

Referring to the drawing, a valve is shown comprising a casing 10 which has a sleeve 10a of cylindrical form having an internally threaded end portion 10b adapted to be attached to the threaded discharge spout 11a, of a liquid container 11 which may contain cream or other liquid to be measured and dispensed. Sleeve 10a has formed thereon a portion 100 of said casing, which portion is bored to have therein a cylindrical chamber 10d. Casing 10 has areceiving port 10c communicating with themterior of the sleeve 10a and a discharge port 10], both of which ports communicate with the bore i or chamber 10d. The casing 10, and specifically the portion 100, is divided along a plane extending substantially diametrically of chamber 100. and at an angle of substantially with the vertical so that said casing has a movable portion 109 which is hinged to the remainder or stationary part of said casing by a hinged pintle 12 so that part 10g is swingable away from the stationary part of said casing as indicated by the dotted lines in Fig. 3. The stationary part of casing 10 has a chamber 10h formed within an enlargement thereon at its upper side, said chamber having openings 102' at either side thereof at its inner or rear ends and said chamber 10h has disposed therein a pair of coiled compression springs 13 having their ends seating against the outer or front end of chamber 10h. A member 14, shown as a substantially rectangular yoke or link formed of a small rod or wire, has one end extending through chamber 1071, and through openings 102' in position to engage the inner ends of springs 13. The other end of yoke'14 has pivoted thereon a'lev'er 15 having a short c'amlike end 15a at one side of its pivot and a handle portion 15b at the other or outer side of its pivot.v Movable part 109 has means thereon in the form of a projection 107' of hooklike form, said projection thus forming a concave recess at its outer and lower side.

A member 16 is provided constituting a shell and said member has a central cylindrical portion 16a adapted to be disposed and fit within chamber 10d and said portion hasan interior chamber with which communicate an inlet port 1622 and an outlet port 160. Member 16 has end members 16d and whilev these might be connected to portion 16a in various ways, in the embodiment of the invention illustrated. they are shown as having hub portions 16fthreaded into the ends of portion'lfia with fine threads. As clearly shown in Figs. 2 and '4, members 16d have flanges which engage the ends of casing portion 100, being of substantially the same diameter as said portion Members 16d have slots formed in their outer sides extending substantially diametrically thereof and the ends of flat bars 17 are disposed in said slots-being secured -.to members 16d by the screws 18, said bars 17 having their outer surfaces flush with the ends of members 16d. Bars 17 converge above member 16, said ends being brought into engagement and secured in a handle member 19 shown as having a ferrule 20 secured to its lower end. The ends of bars 17 are threaded at the outer end of handle 19 and a nut 21 is secured thereon engaging the outer end of handle 19. The flanges of members 16d have shoulders 16c formed thereon and these are adapted to engage when the valve is in discharging position with pins 22 projecting from the. ends of portion 100 of casing 10. When the valve is in closed position, members 1'7 engage the top of sleeve portion.10a. A small central slot 1070 is formed in the outer end of the stationary part of casing 10.

In operation, cream or other liquid tobe dispensed is contained in the container 11 and flows through sleeve 10a. When the valve is in receiving position as illustrated in full lines in Fig. 2, the liquid flows through the port 106 and port 16b which is nowalined therewith into the interior of member 16 or into the chamber in member 16. m It will be seen that at this time outlet port 160 is out of alinement with discharge port; 10). The chamber in member 16,

handle 19 and swings the same outwardly to the position indicated in dotted lines in Fig. 3 or until the shoulders 16e engage with pins 22. Inlet port 16b moves out of alinement with port 106 thus closing communication between member 16 and sleeve 10a and discharge port 160 moves into alinement with discharge port 10 Inlet port 16?) has its edge moved sufiiciently to partially aline with slot 1070. The liquid now flows out through ports 16c and 10 air being allowed to enter the chamber in member 16 through the small slot 1070.

When the parts are to be disassembled, the handle 15b of lever 15 is swung upwardly and lever portion 15a then moves out of engagement with the under side of hook portion 107'. Yoke 14 can now be swung outwardly as indicated in the dotted lnie position in Fig. 3 and portion 109 can swing downwardly to the position indicated in dotted lines in Fig. 3. Member 16 can now be readily removed from chamber 10d. The parts can now be easily and readily cleaned.

When the valve is to be reassembled, mem ber 16'is placed in chamber 10d and portion 109 is swung upwardly to engage and embrace portion 16a so that said portion is now embraced and held between the movable portion 109 and the stationary portion 100 of casing 10. Yoke 14 is now swung downwardly and moves over and embraces projection 107'. Lever 15 is now swung downwardly to the position shown in Fig. 3. End portion 15a engages the under side of projection 109' and yoke 14 is pulled downwardly against the tension of springs 13 and lever handle 15b moves past the dead center position of the end of yoke 14 and is held in the position shown in Fig. 3 with springs 13 under tension. It will be noted that the free end of portion 109 is spaced slightly from the outer end of the stationary portion 100 of the casing and portion 109! is held with resilient pressure in engagement with portion 16a. Portion 16a is thus snugly embraced under resilient pressure and should any wear occur between parts 10 and 16, portion 109 will be moved upwardly by springs 13 and portion 16a will continue to be snugly engaged with the proper fit and pressure. There is thus an automatic take-up for any-wear which should occur.

From the above description it is seen that appli'cant has provided a very simple and efficient structure of measuring valve. The device can bev quickly disassembled without removal of screws or other holding parts. The parts are so constructed that they can be easily and effective- 1y cleaned. The device is maintained at all times in operative condition and as above stated, any wear which'occurs on the moving parts is automatically taken up. The device in practice is suitably plated and polished so as to be quite handsome in appearance. The device has been amply demonstrated in actual practice and found to be very successful and efficient.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth in the parts and combinations of parts disclosed and defined in the appended claims.
